I don’t know, Apple releases a “new” version of macOS with big fanfare every year, and I’ve never heard anyone complain about it as if it were a huge breaking change.

Linux supports it, but (some?) motherboards won’t boot without a display connected. I had this issue recently when I converted my old PC to a NAS and I had to buy a dummy plug.

Podcasts are already hosted by a variety of independent services. Google doesn’t host any podcasts, at least as far as I am aware. In this case it really is a frontend-only problem.

I would subscribe in a heartbeat if I could get a cheaper subscription without youtube music.
